Abstract
Embodiments of multi-host link aggregation are described for active-active cluster implementations. In one or more embodiments, a multi-host LAG bond in the cluster is created with a bond MAC address designated for the bond. Afterwards, a virtual IP address may be created for all hosts within the multi-host LAG bond. Compared with existing active-active cluster implementation, the presented multi-host link aggregation embodiments do not require extra entities, e.g., load balancer or DNS, which could be a failure point or performance bottleneck, thus makes the active-active cluster implementations more efficient and robust. With the Multi-Host LACP bond and virtual IP on all hosts, the cluster may have increased bandwidth to the cluster service and utilize computing capacity in a network switch for improved workload distribution.
